So I got a Holy Diver secondhand and am wanting to put it in my RG7421. I don't have the wiring schematic but was hoping someone could help me out?
Its a 4 connector and looking at what is already in my RG7421 I see that I would be left with 2 wires coming out of the BKP spare. Anyone able to help me out?
This is how the RG7 is currently wired. The red arrow points to the grey wire which is the main wire out of the pickup. The 3 blue arrows point to red and white wires that go to the pickup selector and the ground that's soldered to the pot.

Sorry if I posted in the wrong section (I'm a noob)
